Carlsbad Caverns
I have strong and positive memories of the Caverns from my 1967 vacation with my parents and youngest sister. Rhonda was thrilled with it. When I visited in 1967, they used a variety of colored spotlights on the features, and they were beautiful. Now they are entirely white lights. I asked a ranger about this. She explained the heat was causing mold to develop, so they are now entirely LEDs. Still awesome.

sort of an odd justification. as i recall, at least red, orange, yellow, and green LEDs were available before white. (white LEDs actually being some combination of blue + others, and maybe even non-LED stuff.)
